I picked this mower based on some pretty thorough Internet research. It is the perfect mower for someone like me. I want a neat lawn but I am no handy man and I want a minimum of fuss and bother. There are some negative reviews on Amazon but the criticisms seem unwarranted to me. The mower takes all of five minutes to assemble. It cuts my entire garden [an average residential lot] with lots of charge to spare. The battery charges quickly. I like the fact that it can be removed for charging [ideal over the winter or if you don't have a convenient power outlet] or charged in the mower.
The mower easily cut through some grass that was a little longer than it should be. I did what I would do with any mower, proceed through the area slowly, and I had no problems. I was mulching. I have not used the bag. There are lots of safety features which is important for me since I have a young child.
The mower is quite heavy but much of that weight is in the battery. If you are weak or have a back problem you might not want to take the battery out for charging. However, the self propulsion works wonderfully so using the mower requires very little effort. The mower is quite quiet [your neighbours will be pleased] and, of course, silent when the blade is not running.
If you have an estate this is not the mower for you, but if you have an average sized lot and no desire to store and pour gasoline, breathe in fumes or yank on started cables this is the machine for you!
